Hi all, I've been asked for a HA solution and I've been testing oVirt with a NFS NAS and 2 hosts where I run 2 VMs that have a balancer at their front, each on a different host. Now I'm thinking on the possibility of a host malfunction and my question is: is there automatic migration of the VMs that are running on this host to the other host? Sorry if it is a silly question :-) Alex

Hi :-) I've been migrating VMs using the web administration but I need Power Management on each host so that the engine detects that a host is down, right? Alex

Hi,

Yes, it needs to be fenced. Regarding the topic of this mail which grabbed my attention. when I think about HA and oVirt I think about the following : - oVirt Engine/RHEV-M can failover to an other host - The shared storage is also available on the other side. I've been testing migrating Engine in case it fails in a POC by putting Engine in a KVM VM under control of pacemaker and DRBD to drop the need of shared storage. The storage part is something I haven't found a solid solution for. Maybe with DRBD, but there must be a better way i think. Vincent
